Texas Instruments' MSP430 ultra-low-power microcontroller family includes multiple devices with peripheral sets for a variety of different applications. The architecture, with five low-power modes combined, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and attributes to maximize code efficiency and constant generator. A digitally controlled oscillator (DCO) allows active mode wake-up from low-power mode within 1μs.

The MSP430x21x1 series is an ultra-low-power, built-in 16-bit timer, multi-function analog mixed-signal microcontroller and comparison sixteen I/O pins.

Typical applications include sensor systems that capture analog signals, convert them into digital values, and then process data for display or transmission to the host system.
